How is bond order calculated?

• By multiplying the number of bonding electrons and the number of antibonding electrons.

• By dividing the number of bonding electrons by the number of antibonding electrons.

• By adding the number of bonding electrons and the number of antibonding electrons.

• By taking the difference between the number of bonding electrons and the number of antibonding electrons, and dividing it by 2.
